I have the system connected to an APC Smart UPS 2200. But I do have a few routers, annexes and modem banks connected to it also. I may be reaching the capacity limit of the ciruit. Laszlo On Sun, 31 May 1998, zentara wrote:

Hello everyone!!!

I just want to remind everybody that summer is here, with high air-conditioner loads on the power companies.

If you are experiencing problems such as this one, the first thing to check is low line voltage.

I'm not claiming that it is the source of this particular problem, but it is the first thing to check in the summer. That is unless you have a UPS system going.

Look at the specifications on your power supply, and then monitor your wall socket voltage with a digital meter, or an accurate analog model.

I'll answer below. Since the system refused to stay up, I installed an older kernel verion of Debian, which seems to be stable. But I'd much rather be using the SUSE distribution. See below for the continued blow by blow commentary. Laszlo On Sun, 31 May 1998, Wolfgang Weisselberg wrote:

Are the numbers the same every time or do they cange? Did you compile this kernel?

What does /var/log/messages say about the crashes?

Did the crashes happen around the same time after switching the computer on? Shorter on warm days or with the sun shining on your computer chassis? If yes, it really looks like a heat problem.

The case is located directly in the path of the air conditioner. And the system crashed repeated at night. There seems to enough air circulation since I had a secondary cooling fan installed on the system.

Is your processor cooled properly? Does it's cooling fan turn without squeaky/grinding/etc noises? Does the power supply's fans turn OK?

All fans working, actually the power supply vents are the coolest of any or the many systems running here.

Try it with an open chassis (and some extra ventilators, probably houshold ones ... you *must* ensure a good circulation!), if that helps, it's a heat problem. Also at the time of the crash find out how hot the CPU is (the Cooler may probably not be attached properly). There are stripes aviable that change colour with temperature, they often give good indications.

I will run it with an open case, Since installing the network card, prior to the OS. The case has been on.

Are you 110ure your memory chip(s) is/are OK (no, works under Win does not count, Windows does not use the memory to the full potential)? Try with one half of the chips if possible, or with (a) completely different one(s).

Machine never had windows on it, but the memory seems fine running the debian distributuion. It has been up for almost 20 hours now.

Read /usr/src/linux/Documentation/oops-tracing.txt on how to report this crash.

Going off to RTM.

Reinstalling won't solve many problems under Linux and often does not pay, and *this* is definitely not a problem with packages. It's either the kernel or more probably a hardware problem ...

Hello, I have a little time in Linux (6 months) and just completed my nite class of Intro to Unix, with that I would like to ask some questions. I have two different boxes here, one Linux RH 5.0(b) and just installed BSD 2.2.6 for the experience on my other machine. RH 5.0 provided a GUI from X, in root, called _netcfg_ that enabled me to log into my Netcom ISP which does not provide a static IP for me. It allowed entries for user name, password, primary and secondary DNS numbers, all of which Netcom asks you to use. Seeing that I log in fine, I am dying to find the location of the script it wrote to study for my learning. I also want to see if I can use the script on my other versions of Linux / Unix that I intend on trying. Any ideas. -- Bill Schoolcraft PO Box 210076 San Francisco CA 94121 <A HREF="http://www.netcom.com/~wiliweld"><A HREF="http://www.netcom.com/~wiliweld</A">http://www.netcom.com/~wiliweld</A</A>> -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
